LOUIS MOZOLAN, OF MONTGOMERY, ALABAMA.

LIQUID-LEVEL-ALARM APPARATUS.

Application filed June 5, 1914.

To all whom it may concern Be it known that I, LOUIS MOZOLAN, a citizen of the United States, residing at Montgomer in the county of Montgomery and State of Alabama, have invented new and useful Improvements in Liquid- Level- Alarm Apparatus, of which the following is a specification.

This invention relates to improvements in liquid level alarm apparatus and, in the present instance, is directed particularly to an apparatus of the class described for use in conjunction with the drip pans of refrigerators and the like.

In carrying out the present invention, it is my purpose to provide a liquid level alarm apparatus which will embody among other features, a horizontal lever disposed within the liquid container and having one end fulcrumed and the opposite end equipped with a float and a signal under the control of such lever and adapted to be actuated when the float end of the lever has been elevated to the predetermined point, means being provided for adjusting the fulcrum end of the float carrying lever vertically so that the float may be elevated or lowered according to the movement of the fulcrumed end of the lever.

It is also my purpose to provide apparatus of the type set forth which will embrace the desired features of simplicity, efficiency and durability, which may be installed and maintained at a minimum expense and which may be employed wherever it is desired to give a signal upon a body of liquid reaching a predetermined level.

IVith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts here inafter set forth in and falling within the scope of the claim.

In the accompanying drawings, Figure 1 is a diagrammatic view of a liquid level alarm apparatus constructed in accordance with the present invention, the drip pan or liquid container being shown in side elevation. Fig. 2 is a longitudinal sectional view through the drip pan showing the mechanism therein in side elevation. Fig. 3 is a transverse sectional view through the pan. Fig. 4 is a perspective view of the adjusting bar for the float carryinglever. Fig. 5 is asimilar view of the connection between the float carrying lever and the circuit closer.

Serial No. 843,298.

Referring now to the drawings in detail, 1 designates a drip pan adapted to be placed beneath a refrigerator or the like to catch the drainage water. Located at some convenient place is a signal 2 which, in the present instance, is in the form of an electric bell and this bell is connected in an electric circuit 3 including a suitable source of energy as a battery 4: and a circuit closer 5. In this case, the circuit closer is in the form of a push button and holds the circuit 3 normally open so that the signal, under nor mal conditions, remains inactive.

The circuit closer 5 is preferably secured to one side wall of the drip pan 1 adjacent to the top edge of such wall and upstanding from the bottom wall of the drip pan adjacent to the circuit closer is a standard 6 and pivoted to the upper extremity of the standard 6 is a horizontal arm 7 having one end thereof upturned as at 8 and engaging the circuit closer 5 and the opposite extremity extended upwardly as at 9. Pivotally connected between its ends with the upwardly extending end of the arm 7 is a lever 10 and connected to one extremity of the lever 10 is a float 11, while pivoted to the opposite end of the lever and depending therefrom is a fulcrum post 12 forming the fulcrum point of the float carrying lever 10. Slidably mounted within horizontally alining guides 13 secured to the bottom wall of the drip pan and arranged transversely thereof is an adjusting rod 14 having the opposite ends thereof formed to provide eyes 15 and the center portion formed with an eye 16 through which is passed and secured the lower extremity of the fulcrum post 12.

In practice, the lever 10 normally lies in a horizontal plane and when the level of the liquid within the pan 1 reaches the float 11 the latter is carried upwardly and in the continued upward movement thereof the lever is swung about its pivotal connection with the post 12 thereby swinging the arm 7 with the effect to depress the upturned end 8 thereof and so release the circuit closer 5 to close the circuit 3 and sound the alarm. When it is desired to adjust the apparatus so that the point at which the float is engaged by the rising liquid may be varied, the adjusting rod 14 is slid within the guides 13 thereby moving the fulcrum post 12 to lower or elevate the fulcrum point of the float carrying lever. lhus, the float may be adjusted to actuate the circuit closer at different liquid levels.

From the foregoing description taken in connection With the accompanying drawings, the construction, mode of operation and manner of employing my invention will be readily apparent. It Will be seen that I have provided a liquid level alarm apparatus whereby a signal Will be given When the level of the liquid Within the container reaches a predetermined point and wherein the liquid actuated mechanism may be adjusted so that the signal may be actuated at different liquid levels,

While I have herein shown and described one preferred form of my invention by Way of illustration, I Wish it to be understood that do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made ithin the scope of the claim Without departing from the spirit of the invention.

1 claim:

In a float actuated circuit closer, a pan, a circuit closer secured to said pan, a horizontal lever within said pan, a fulcrum post connected to one end of said lever, a float on the other end of said lever, a horizontal arm pivoted Within said pan and having one end in engagement with said circuit closer, a connection between the other end of said arm and lever whereby said circuit closer will be influenced to close the circuit as the fluid level rises, guides secured to the bottom Wall of said pan, a horizontal rod slidably mounted Within said guides, and a connection between said rod and fulcrum post whereby the fulcrum point of said horizontal lever may be changed.

In testimony whereof I affix my signature in presence of two Witnesses.
